| Abstract: |
Elevated temperature and unusual rain is adversely affecting agricultural crops. Threats in the
rice crop due to temperature rise are: change in crop phenology, physiology, grain yield and
even crop success along with moisture and nutrient availability. An experiment was carried
out in field and open top chamber (OTC) to study the response of rice variety (Khumal 4),
C02-C emission under different temperature regime and different dates of transplanting (19th
June, 29th June, 9th July) in 20 I 0 and 2012. Experiment showed that heading and maturity
were 4-7 and I 0-12 days earlier in OTC .Average grain yield was higher by 9.2% in OTC.
Higher average grain yield was recorded in 3'd date of planting under both conditions.
Average daily temperature was 4-5°C higher in OTC. C02-C emission under OTC was nearly
24% higher compared to field, whereas organic carbon in OTC was lower compared to field.
Thus, yield can be increased under elevated temperature and unusual rainfall with proper
water management practices. Therefore, a strong monitoring system on climatic parameters
and their impact on crop have to be regulated to increase rice crop production. |
